Another interesting note, the Tannoy true point-source Dual Concentric©
monitors are free from
the physical offsets previously described, which means that the behavior of the Dual Concentric
monitors will not change in the horizontal, vertical or any other plane you can pick. The other neat
thing about Dual Concentric
monitors is that no matter how close you get to them you can’t get
the image to fragment into separate high and low frequency sources.
Now, if you were to follow the all too common practice of lying your two way monitors on their
side to give you better sight lines over your meter bridge, you can see (and hear) what will
happen. With the monitor on its side, moving your head horizontally means you are now moving
through all those rays, or lobes, where the wavefronts from the woofers and tweeters interfere
with each other. The midrange frequency response will be different for each head position. All two
way component monitors, no matter who manufactures them, need to be used with the multi-
driver axis vertical (that’s just the way it has to be when you’re in the near-field). And if you’re
wondering how three-way near-fields work with a whole bunch of speakers stuck all over the
baffle, well... you’ll quickly realize why we stopped at two way speaker systems.
